This is the sun-moon dynamic of iOSsphere rumors: The sun rises on one rumor, and then the moon rises on the opposite rumor. Recently, the rumor was that the iPhone 5 will also launch on Sprint, which of course doesn't yet offer any iPhone.

This week, the rumor is that Sprint will begin offering the iPhone 4, and in 2012 will offer iPhone 5. TUAW.com's that a "Sprint Nextel sales associate told TUAW that the carrier has started briefing its employees on an imminent Sprint iPhone 4 launch."

The source said the sales team was told that Sprint will have iPhone 4 available in October with standard Sprint data plans. "If the associate's information is accurate, Sprint will not get the iPhone 5 until 2012, most likely by early spring," Sadun writes.

Interestingly, the source also told TUAW that Sprint "will carry a 4G , though launch dates and pricing were still unknown." Obviously, there is not a "4G iPad" product currently. But before you get your hopes up, Sadun notes: "Sprint already sells 4G access for the iPad via its external mobile 4G WiFi product; maybe that's what the briefing referenced." It's an intriguing example of the inner dynamics of iOSsphere "information."
